Account banned for verifying email

I just signed up for Netlify and once I confirmed my email address I was told that the account was suspended:

"We have suspended this account due to suspicious activity. "

I have just signed up and confirmed my email, I have never used the account.
What suspicious activity are you referring to?
Signing up to be a customer?

Hi, your account were automatically marked as spam as an effort to crack down on potential fraudulent behaviour. Please see our VP of security response regarding this.

Luckily, you should now be able to verify yourself via stripe to unlock your account. Please try signing in again and follow the prompts to upload a copy of your ID so we can be sure you are legitimate. Please view a list of acceptable documentation for your country here. If you are not prompted to do this please submit a support ticket and mark the reason as “signup/login”.

If you do not want to verify your ID you can bypass this step by signing up for a Pro tier account.
